Your question sounds to me as if you're looking for in-game chat commands with which you can control an allied AI. Nexus AI only supports "help!". NullBot AI chat commands are documented in the first message of the respective thread.

If you're actually looking for AI script documentation, see the Scripting sub-forum's sticky threads. That'd give you info about the modern JavaScript API that was used for developing NullBot. The original/old API is pretty much deprecated by now, and kept around only for historical reasons, you shouldn't spend time with trying to code with it because it's a pain.

I'll see what I can find in there and compare it to what I'm seeing in the AI to see if anything is missing. Speaking of AIs is there a way to get around that 10 AI display limit floating around on the forum somewhere?
